Title: Application of CPR imaging technique of MSCT in facial nerve canal
Abstract: Objective:To apply MSCT volume scanning and explore the displaying ability of CPR(curved planar reformation) imaging technique of MSCT in the panorama of facial nerve canal and the size and the diameter of each section.Methods:Forty-five cases,who were administered inner ear examinations between June 2011 and March 2012 and found no abnormality in temperal bone,were randomly selected to have high resolution MSCT volume scanning on the part of temperal bone.All the acquisition data were processed by the means of ultra-thin layer raw data magnification and sent to the image post-processing worker-station to complete the curved planar reformation of the bilateral facial nerve canals measuring the size,the diameter,and length of each section.Result:Among the 45 cases,89.90 % of them(40 cases,90 ears) could completely display the bilateral facial nerve canals and the size,the diameter,and length of each section could be accurately measured.Three cases(6.7%) could only display the unilateral facial nerve canal,and two cases(4.4%) displayed none of the bilateral facial nerve canals.The length of labyrinthine segment,tympanic segment,and mastoid segment of the facial nerve canals had a total length on the left and right of(3.66±0.31) mm,(11.55±1.15) mm,(13.51±1.08) mm,(26.32±2.61) mm,and(3.53±0.23) mm,(11.24±1.21) mm,(13.12±1.24) mm,(26.73±2.31) mm,respectively.The size and the diameter of the labyrinthine segment,tympanic segment and mastoid segment of the facial nerve canals had a total length on the left and right of(0.82±0.11) mm,(1.15 ± 0.12) mm,(1.18±0.14) mm,(3.09±0.11) mm,(0.79±0.13) mm,(1.23±0.15) mm,(1.21±0.15) mm,and(3.15±0.22) mm,respectively.Conclusion:The CPR imaging technique of MSCT has a significant value in the display of the imaging anatomy of facial nerve canal and provides a theoretical foundation for the confirmation position diagnosis of lesions of the facial nerve.
